I agree, one of the things the algorithms on centralized platforms do so well is help new users be discovered. You join twitter/instagram/tiktok and they do their best to promote that new user to people who they share contacts with. They highlight their posts so they get likes, follows, replies. That way new users don’t feel like they’re talking in to a void.

This is hard because you need to balance this out with not rewarding spammers. It’s one of the hard problems we need to solve, and it’s not one existing users see, but it’s important.
